TI introduces new line of functionally isolated modulators

Texas Instruments (TI) has introduced the industry’s first functionally isolated modulators, helping designers achieve more precise motor control in compact robot designs. The new AMC0106M05, AMC0136 and AMC0106M25 isolated modulators enable increased precision and higher resolution of 12 to 14 effective number of bits (ENOB) for accurate and reliable phase current sensing and DC voltage sensing measurements. Offered in a small lead-less package, the new products in TI’s isolated analog-to-digital converter (ADC) portfolio help designers achieve smooth torque operation and fine motor control, while decreasing size and cost in low-voltage (<60V) robotics designs.

Engineers today are challenged to design smarter robots to perform more detailed tasks. The galvanically isolated modulators enable robotics engineers to achieve precise motor control and system protection in smaller, more sophisticated designs. This precision makes it possible for robots to complete a variety of complex tasks, such as threading a needle or handling small nuts and bolts. In addition, the small size of the new modulators—measuring just 3.5mm x 2.7mm—requires 50% less board space than competing reinforced isolation solutions. With this decrease in size, designers have more space to incorporate additional features that support precise control and reliable operation in compact robot applications.

“These modulators from TI enable designers to increase robotics accuracy and productivity in new use cases and smaller form factors, from the factory floor to the operating room,” said Karthik Vasanth, vice president and general manager of Data Converters and Clocks at TI. “For example, where humanoid robots could previously only complete simple tasks, our new functionally isolated modulators now allow them to carry out more dexterous and precise jobs.”

Production quantities of the new functionally isolated modulators are available now on TI.com in an 8-pin very thin small-outline (VSON) package. To support designers, evaluation modules for all three modulators are available, as well as reference designs and simulation models.

Intel accelerates AI at the Edge through an open ecosystem

Intel is unveiling its new Intel AI Edge Systems, Edge AI Suites and Open Edge Platform initiatives. These offerings help streamline and speed up AI adoption at the edge across industries such as retail, manufacturing, smart cities, and media and entertainment by simplifying integration with existing infrastructure.

With over 100,000 real-world edge implementations with partners, many leveraging AI today, Intel understands the unique challenges of edge AI. These challenges vary significantly by industry, with each having distinct performance and power needs. What works for cloud providers is not suitable for enterprises at the edge, which need to maintain existing platforms and software, while integrating AI, to get the best total cost of ownership (TCO) and power efficiency.

Unlike large data centres with dedicated AI infrastructure, edge AI deployments must seamlessly integrate into preexisting IT systems in space-constrained, low-power and cost-sensitive environments.

Intel AI Edge Systems, alongside Edge AI Suites and the Open Edge Platform, address these challenges by building on Intel’s pervasive technology foundation at the edge. These efforts empower the ecosystem to bring edge AI to market faster and more efficiently.

The open edge approach allows Intel to deliver better end-to-end performance and overall TCO in a variety of key industries. In an edge AI video analytics use case, tera operations per second (TOPs) alone don’t deliver real-world performance needs. When comparing Intel Core Ultra processors to leading AI competition, although competition may lead in TOPs, Intel delivers up to a 2.3x increase in end-to-end pipeline performance, and up to 5x better performance per dollar2.

While many edge deployments today incorporate AI using traditional machine learning and computer vision, Intel’s AI Edge Systems, Edge AI Suites and Open Edge Platform are designed to accelerate the deployment of advanced AI applications. Through a robust ecosystem of trusted partners, Intel enables enterprises to tackle industry-specific challenges and drive innovation in edge AI deployments.

Intel’s edge systems speed up AI deployment at the edge. Builders – original equipment manufacturers (OEMs) and original design manufacturers (ODMs) – have access to standardised blueprints, benchmarks and verification tools optimised for edge AI use cases. These resources enable customers and solution providers to easily configure systems to meet the performance needs of use cases like vision AI or generative AI (GenAI). With a range of power levels, sizes and performance options, these solutions ensure optimal integration of hardware and software.

Edge AI Suites: Edge AI Suites are open, industry-specific AI software development kits (SDKs) for independent software vendors (ISVs), system integrators and solutions builders. These suites simplify the creation of custom AI solutions for various industries by providing curated reference applications, sample code and benchmarks to accelerate application development. Currently, Intel offers four suites, optimised for retail, manufacturing, smart cities, and media and entertainment.
Open Edge Platform: The Open Edge Platform is a modular, open source platform that simplifies the development, deployment and management of edge and AI applications at scale. With cloud-like simplicity, this platform allows ISVs, solution builders and operating system vendors to integrate software components efficiently and leverage performance optimisations from Intel’s latest software advancements. Partners can easily deploy containerised workloads on remote edge devices — without the need for on-site visits — and manage these deployments with tools like Intel vPro®/Intel® Active Management Technology, enabling collaboration and innovation across the software ecosystem.

Renesas unveils Lithium-Ion battery management platform with pre-validated firmware

Renesas has introduced all-in-one solutions for managing lithium-ion battery packs in a wide range of battery-powered consumer products, such as e-bikes, vacuum cleaners, robotics and drones. With pre-validated firmware provided, the R-BMS F (Ready Battery Management System with Fixed Firmware) will reduce the learning curve for developers, enabling rapid designs of safe, power-efficient battery management systems.

Designed for lithium-ion batteries in both 2-4 and 3-10 cell series (S), R-BMS F solutions include Renesas’ fuel gauge ICs (FGICs), an integrated microcontroller (MCU) and an analog battery front end, pre-programmed firmware, software, development tools and full documentation – all available in complete evaluation kits that are now ready to ship.

Firmware is essential in battery management systems as it is used to monitor batteries’ state of charge (SoC), state of health (SoH), current, and temperature, as well as actively balancing the voltages of the individual cells, and detect faults. In some cases, however, consumer electronics developers may lack the highly specialised expertise needed to develop control algorithms that keep the batteries operating in a safe temperature region and ensure adequate battery life over many charge/discharge cycles.

Renesas’ R-BMS F solutions include built-in, pre-tested firmware designed to work with the FGIC’s on-board MCU. The firmware includes critical pre-programmed functions to maximize battery life and ensure safe operation. These include cell balancing, current control, and voltage and temperature monitoring. For added flexibility, the battery management system lets developers set many parameters to meet specific requirements and adjust the solution for different cell chemistries via a graphical user interface (GUI), without the need for a full integrated development environment (IDE).

Both R-BMS F solutions contain a full evaluation kit, which has all the hardware, software, tools and documentation required to start developing. The underlying hardware powering the R-BMS F is Renesas’ FGIC solution, which combines an analog battery front end and an ultra-low-power RL78 MCU into a single, small package. The analog portion provides accurate measurements of cell voltage, current and temperature, as well as controlling the external MOSFETs and converting analog data to digital signals. The digital section is where synchronous functions reside, including the main CPU, clocks, timers and serial interfaces. Also included in the evaluation kits are: pre-programmed firmware stored in embedded flash memory with the flexibility to set the battery pack and cell chemistry parameters; the USB System Management Bus (SMBus) interface; GUI-based software; cables to communicate with the host system; dedicated development tools for parameter setting; and full documentation, including schematics and an engineering bill of materials (eBOM). With these resources, developers can confidently innovate intelligent power management systems that safely monitor battery usage and provide longevity, while reducing their impact on the environment. Renesas plans to include turn-key R-BMS F solutions in all future FGICs.

The R-BMS F for 2 to 4S cell (~8V to 16V) solutions targets small vacuum cleaners, robotic vacuums, consumer and medical devices and runs on Renesas’ RAJ240055 Li-ion battery FGIC. Renesas offers Smart Robot Vacuum Cleaner | Renesas by combining this FGIC with other devices from its portfolio.

The R-BMS F for 3 to 10S cell (~12V to 40V) solutions runs on Renesas RAJ240100 and RAJ240090 Li-ion battery FGICs, with target applications including e-bikes, e-mobility, vacuum cleaners, robotics, drones and industrial, consumer and medical systems.
